Hammer Logan was an early civil rights leader known for his violent protests, but he transformed after being imprisoned and encountering Willem Robertson. Upon his release, Logan organized peaceful protests through methods like boycotts and marches. His most famous was the March on Chicago, which drew over 75,000 people and was praised by Martin Luther King Jr. for its nonviolent approach. Late in life, Logan was fatally shot by members of his original protest group who disagreed with his embrace of nonviolence.
